save2600 is right. This does not include a SCSI interface. It has a PSU for the hard drive, activity LED and pass through port (Centronics 50 port).
I have one more IBM 520 Mb SCSI hard drive (used, but only a few hours on it).
PM me for a price
Wouldn't you know my camera is acting up. I will try to get more pics up, asap
